I said I wasn't going to say anything more about the Canon 5D MkII and less than an hour later I discover that the video shot by Vincent Laforet is available on Canon's site.
It's all pretty amazing and beautifully shot, but right at the end, there's a pan across the New York skyline and there definitely seems to be something going on there (though it could be enhanced by the shake of the helicopter.) Hard to tell. But there's a lot of other shots (several with the camera in motion) where you don't notice anything.
Definitely check it out.
